Thank you for the feedback! <3
About the FPS map, there were no points of interest that could help navigate. Maybe I should have added some unique items to mark the locations or maybe even some arrows to help. Sadly I didn't think about that then, sorry.
I believe the match3 controls are common to the style, but it's true that I forgot about the click indicator. I made another game where you click twice to match, but in this one the pieces don't have to be adjacent. That's also why I did it like that this time, click and release.
